MINER, INC, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE DOOR-OPERATING MECHANISM Application filed March 31, 1927. Serial No. 179,818.

This invention relates to door operating mechanisms.

An object of the invention is to provide a door operating mechanism for use in connection with a railway car, including a frame member and a sliding door member and wherein a bracket provided with a vertically extending slot is secured to one of said members and is adapted to be engaged by an actuating portion forming part of a lever pivotally mounted upon the other of said members, whereby swinging movement of the lever forces the door in opening and closing directions, means being provided for co-operation with the operating mechanism whereby a latch member on the lever is utilized for looking the door in fully or partly closed positions.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

Referring to the drawings forming part of this specification, Figure 1 is a side elevational view of a fragment of a door frame and sliding door of a railway car, showing the invention applied thereto, the door being locked in fully closed position. Figure 2 is a view similar to Figure 1, showing the invention operating to lock the door in partially to open position. Figure 3 is an enlarged traverse vertical sectional View taken on a line corresponding substantially to line 3-3 of Figure 1. Figure 4 is an enlarged horizontal sectional view of the invention on the line 4c of Figure 1. And Figure 5 is a horizontal sectional view corresponding substantially to the line 55 of Figure 1.

As shown in the drawing, 10 denotes a portion of the door frame of a railway car, said frame being provided with a rabbet 11 adapted for the reception of the forward edge of a sliding door, a fragment of which is indicated by the numeral 12. Secured to the frame portion 10 by means of bolts 13 is a bracket 4 1 1. Said bracket is provided with an extension 15 overhanging the rabbeted. portion of the frame member 10, as best shown in Figure 1. The extension 15 is provided with a vertically extending channel or groove 16 open at the bottom as indicated 17 and closed at the top as indicated at 18. The bracket 14 is further provided with a depending portion 19 having an angular horizontally disposed projection 20 provided with an aperture 21 adapted for the reception of a securing bolt hereinafter referred to.

Mounted upon the door member 12 by means of bolts 2222 is a horizontally arranged strap 23, the rear end portion of which is provided with an upstanding keeper 24; having an opening indicated at 25 for the reception of a securing bolt as hereinafter referred to. The strap 23 adjacent its forward end is provided with a socket portion 26 adapted for the reception of a boss 27 formed on the lever 28, the lever being pivotally secured to the strap 23 by means of a rivet 29, the inner head of which is accommodated in a cut-out portion 30 provided in the face of the door. At one side of the pivot pin the lever is formed with a laterally extending actuating portion 31 adapted to enter and leave the channel 16 through the entrance 17 and to bear upon the walls of the groove or channel in effecting movement of the door in opening and closing directions when the lever is operated.

At the opposite side of the pivot pin 28, the lever is provided with an angularly off-set section 32, and provided with a guide means comprising curved portions 33'33, and an opening 34 in the ofi-set section 32, the section 32 and guide means being spaced apart, and each provided with laterally extended spaced lugs 3535. Slidably and rotatably mounted in the guide means and section 32 is a locking bolt 36, said bolt being provided with a laterally extending lug 37 adapted to be moved into position between the lugs 35-35 in one position of the parts. When the lug 37 is rotated from a position between the lugs 35-35 the bolt may be moved in a longitudinal direction and is adapted to engage either the keeper 20 on the bracket 14 or the keeper 24 on the strap 23, depending upon i the position of the lever, the bolt being held against complete removal by the outer head of the rivet 29 when movedin one direction and by the offset 32 when moved in the oppo site direction. The lugs and 37, are

provided with apertures 38 adapted for the reception of a sealing device, not shown.

In operation, assuming the door to be in closed position, with the lower end of the locking bolt 36 engaging the keeper 20, and it is desired to open the door, the sealing member which may be extended through the lugs 35-35 and 37 is broken, and the bolt 36 rotated so as to disengage the lug 37 from between the lugs 3535, after which the bolt may be raised, freeing the same from the keeper 20. Swinging movement of the lever in a counter-clockwise direction brings about movement of the actuating portion 31, which bearing against the left-hand wall of the groove or channel 16 forces the door in an opening direction. If it is desired to lock the door in partly open position, the lever is moved in a counter-clockwise direction a sufiicient distance just short of moving the actuating portion 31 from the channel 16, thereby positioning the bolt 36 whereby the same may be moved toward the free end of the lever into engagement with the keeper 24:, after which the lug 37 on the bolt may be rotated into position between the lugs 3535 formed on the lever and a sealing member passed through the openings of the lugs, the door thereby being locked in partially open position. If it is not desired to lock the door in partly open position, the actuating portion 31 is moved completely out of the channel 16, and the door 12 pushed by hand to fully open position. In closing the door 12, the same is moved forwardly toward the frame member 10 until such time as the engaging portion 31 may be inserted into the channel16, after which the lever may be moved in clockwise direction, forcing further closing movement of the door 12, by reason of the engagement of the ac-- tuating portion 31 of the lever with the right-hand wall of the groove or channel 16 of the bracket 14. l/Vhen the lever reaches a substantially vertical position, the locking bolt 36 will be in position so that the same may be engaged with the keeper 20, after which the bolt may be rotated to position with the lug 37 thereon between the lugs 3535 on the lever, and a sealing member extended through the lugs 3535 and lug 37.

While I have herein shown and described what I consider the preferred manner of carrying out the invention, the same is merely illustrative, and I contemplate all changes and modifications which come within the scope of the claims appended hereto.
